Abstract (en)
[origin: EP0631978A1] Removing hydrogen sulphide from a gas stream (4) comprises contacting the gas stream in the presence of free oxygen at a temperature in the range of from the dew point of water to the dew point of elemental sulphur in two catalytic reactors (1 and 2) with catalytic material to obtain elemental sulphur which is deposited on the catalytic material and a purified gas stream, wherein the gas stream is contacted in the first catalytic reactor (1) with catalytic material in the presence of a sub-stoichiometric amount of free oxygen to obtain a partly purified gas stream (20d), which partly purified gas stream (20d) is contacted in the second catalytic reactor (2) in the presence of an additional amount of free oxygen with catalytic material to obtain the purified gas stream (5). <IMAGE>
